Mr. Olympia is title awarded to the winner of the professional men's bodybuilding contest at Joe Weider's Olympia Fitness & Performance Weekend-an international bodybuilding competition that is held annually by the International Federation of Bodybuilding & Fitness (IFBB). Joe Weider created the contest to enable the Mr. Universe winners to continue competing and earn money. The first Mr. Olympia was held on September 18, 1965, at Brooklyn Academy of Music, New York with Larry Scott winning his first of two straight titles.

The record number of wins is eight each by Lee Haney (1984-1991) and Ronnie Coleman (1998-2005). Shawn Rhoden currently holds the title.

The film Pumping Iron (1977) featured the buildup to the 1975 Mr. Olympia in Pretoria South Africa and helped launch the acting careers of Arnold Schwarzenegger and Lou Ferrigno.

There is also a female bodybuilder crowned, Ms. Olympia, as well as winners of Fitness Olympia and Figure Olympia for fitness and figure competitions. All four contests occur during the same weekend. From 1994 to 2003, and again in 2012, a Masters Olympia was also crowned.

Starting in 2016, a new division called Classic Physique was introduced. Danny Hester was the inaugural champion in Classic Physique division.
